2. Application filed November e, 1926. Serial No. 146,597.

The general purpose of the invention is to provide apparatus for delivering annular objects into engagement with .the moving parts of a machine to have an operation of any character performed thereon, and then for removing said objects from the machine, within the control of' an operator, but without thedangerous manual handling heretofore practiced. For purposes of illustration, the feeding device will be described as used in connection witha machine for rolling rims for pneumaticautomobile tires, the rim being fed into, the roller in, an approximately I annular fiat band form and being removed after it is rolled to true annular form and with the desired side flanges. 2

One object is to provide means for feeding blank rims into a roller andsimultaneously removing a rolled rim from said rollers. Another object is to provide means for feeding, a blank rim between a pair of rollers and for simultaneously urging said rollers together to, roll said; rim to any desired contour, Another object is to provide fluidoperated means for feeding rims into ro 1ling machines and removing the same therefrom. A further object isto provide a feeder armtov support rims which are somewhat eccentric or out of round.

. The foregoing and other. objects are obtained by the apparatus; illustrated in the accompanying drawings and described below. It is, to. be understood that the invention is not limited to use with the particular, machine described nor limited to the specific form thereof shown and described.

Of the accompanying drawings:

Figure 1 is a frontelevation of a device embodying the invention illustrating the same: in position to; remove a rim. from a rollingwmachine;

Figure2. is a, plan,v thereof showing only the lower roll of the rolling machine; and

Figure 3 is a plan. view of the device in' its position. after a rim is removed from the rolls and another one fed therebetween, a part of the. device. being broken away.

Referring more particularly to the draw ings, 10 represents the frame of a rolling machine, an example Of a suitable. ma chine connection with. which the mven:

t-ion may be used, and 11 and; 12 are the rolls thereof; Ablank rim 1-3 to, be rolled is represented by a dotted line and is shown supported by a feeder arm 14:, while a finished rim.13 is shown supported by a removing arm 15. Arms 14 and 15 are attached to vert-ical shafts 16 and 17, respectively, which are journaled in brackets 18, 1 8 and 19,19 mounted" on frame 10, the arms being thus mountedto swing toward and from the roll 12. A pair of journals 20, 20 and 21', 21 areadjustably mounted along arms 14 and 15 and have pivoted thereon at 22, 22 and-23, 23 brackets 24, 2A and 25, 25. The upper and lower ends of each. bracket have mounted at-right angles thereto a finger 26, the fingersonl arm 14 being adapted to carry a, rim and place it upon roll: 12 when arm 14 is swung toward said roll and the fingers arm 15 being adapted to engage, the rim and remove it from said roll when arm 15 is swung away therefrom. Suitable mechanism is provided for limiting the pivotal movement of' brackets 24-, 24 and: 25,, 25, the form illustrated i ets 32 and 33 mounted on shafts 16" and 17 respectively, said chain being tightened a suitable idler 34'. desired, arm 1 1 may be made to. swing through a lesser angle. than arm 15 by makingusprocket 32 larger than sprocket seas illustrated IArm 1e will thus swing from its position in Figure 2 to its position in Figure 3 whilearm 15 isswinging through ahalf cirele,in which former position of the ar1n14-,the rim 13 may more readilybe placed on the arm by the operative and need travel but a short distance before engaging the rolls.

ihe ms may e operated y manually w n ing. m 1 t re Pref y eet ated by air cylinder" mounted on a suitable base 36 and controlled by a fourway valve 37. Piston 38, reciprocable in cylinder 35, is connected by'piston rod 39 to a gear rack 40, which rotates shaft 16 by meshing with a pinion 41 keyed thereon.

In order to operate the rolls 11 and 12 to urge them together in timed relation to the feeding of the rims, a valve 42, connected to a hydraulic rollraising cylinder (not'shown), is mounted on base 36 and is actuated by piston rod 39.

A standard 48 is attached to the floor: as shown in Figure 3 and has an overhang-ing end 44 adapted to engage the top of rim 13 to ect the same from arm 15 as the latter completes its outward swing.

In the operation of the apparatus, the operative places a blank rim on the fingers 26 of arm 14 and opens valve 3'7 to admit air pressure to the right end of cylinder 35 to move piston rod 39 to the left, swing arm 14 inwardly and deliver the rim between the rolls of the rolling machine, while arm 15 is swung outwardly to remove a previously rolled rim. At the same time, valve 42 is also actuated by piston rod. 39 to admit water pressure to the hydraulic cylinder to raise lower roll 12 and force it against the rim and the rim against upper roll 11. lVhen the rolling operation is finished, the operative throws the valve 87 over, whereupon air cylinder operates to withdraw arm 14 and swing arm 15 inwardly to receive the finished rim. At the same time valve 42 is shifted to reverse the hydraulic cylinder and lower theroll 12 or fiat-sided due to preliminaryrough rolling sway when first placed in the rolls.

, tions performedon the rim after it has been I and welding, they have considerable side In order that the supporting means may sway with the rim without bending the rim or breaking the supporting arms, bracke ts 24,

24 are pivoted and are resiliently held in position by springs 29. Brackets 25, 25 may be likewise pivoted to have a yielding grippingraction on the finished rim. 'On operarolled to true annular form, the pivoted brackets may be dispensed with and other means used to support the rim" as will be understood. on

A simple and effective means is thus pro vided for feeding annular objects into maclnnery and removing the same therefromafter an operation has been performed thereon. Dangerous manual operations are thereby elimmated and, due to the device being .practically automatic, it eliminates considchine, said shaft being journaled to swing said arm into and, out of alignment with said rolls to deliver a blank rim therebetween, a

second supporting arm attached to a vertical shaft, said'shaft being journaled to swing said second arm out of and into alignment with said rolls, successively and alternately with. said first arm, to remove a rolled rim from said rolls, a large sprocket keyed to said first-mentioned shaft, a smaller sprocket keyed to said last-mentioned shaft, a chain connecting said sprockets, whereby said arms may be swung in definite. angular relation to each, other andthe delivering arm swung through a lesser angle than said removing.

arm, means for swinging said arms, comprisving a double-acting air cylinder having attached to the piston rod thereof a gear rack meshing with a pinion keyed to said firstnamed shaft, a valve shiftable by said pistonrod for controlling the relative movement of said rolls in timed relation to the rim-delivering operation, a manually operable valve for controlling said air cylinder, and a standard for ejecting a rolled rim from the second supporting arm as the latter is swung away from said rolls.

2. In combination with a machine adapted to perform an operation on annular objects,

a means for delivering said objects to said machine and for removing the same therefrom, comprising a pair of oscillatory object. supporting armsadapted alternately to be swung into engagement with said machine, means for swinging said arms comprising a fluid operated cylinder, a rack and pinion connect-- ing said cylinder and one of said arms and a chain engaging sprockets on the two arms, means for controlling the operation of the machine in timed relation with the delivering of said objects, comprising a valve actuated by said cylinder, and means for ejecting an object from the arm removing said object from the machine. i

I 3. A feeder arm for delivering annular objects to a machine, said arm comprising an oscillatory member, journal members adj ustably mounted thereon, a bracket pivoted on each journal member, and means for resiliently limiting the pivotal movement of said bracket, whereby the brackets may yieldingly grip'objec'ts which are somewhat eccentric.

I 4. The combination with a machine having relatively movable elements, of a feeder arm and said carrier arm out of cooperative relapivoted to one side of said'maohine for detion with said element, and means for conlivering Work into operative engagement trolling the operation of said machine on said 10 with one of said elements, a carrier arm piv- Work in timed relation to the work delivering 5 oted to the other side of said machine for operation.
